Estimation of extreme values of the Weibull distribution

Bargaoui, Z.K., 1993: Estimation of extreme values of the Weibull distribution. Extreme hydrological events: precipitation, floods and droughts: proceedings of the International Symposium held at Yokohama, Japan, 20-23 July 1993: 217-226

Several method for the estimation of Weibull distribution parameters were applied for frequency analysis of annual rainfall data from the north of Tunisia. The methods produced significantly different quantiles for extreme values in the left and right tails of the distribution. Estimation methods were also compared with respect to the width of the confidence intervals obtained. The method of mixed moments gave the minimum square root errors for quantiles less than the median of the population.
